Short description Identification keys | Morphology | Morphometrics

Vertebrae: 131 - 138. This species is distinguished by the following characters: presence of pectoral fin; dorsal-fin origin above middle of pectoral fin, predorsal length 11.5-15.0% TL; the lower jaw is longer than upper jaw, slightly curved and not appressed to upper jaw when mouth closed; anus anterior, below pectoral fin, preanal length 15.4-17.3% TL; trunk is very short, trunk length 3.0-5.3% TL; no intermaxillary teeth; multiple rows of teeth on upper jaw, those on innermost row about twice the size of the rest; 5 or 6 (mainly 5) compound teeth on vomer; multiple rows of teeth on lower jaw, the innermost row about twice the size of the rest; head pores: IO 4, SO 3, M 7 (1 with 8), POP 0, AD 1, F 0, ST 0. Lateral-line pores very large, predorsal 10-13, prepectoral 8-11, preanal11-17, total pores 107-117, the last to 1/2 HL before the caudal-fin base. MVF 13-14-135, total vertebrae 131-138; colour of body uniformly light pinkish to grayish with numerous melanophores, posterior margin of anal fin and caudal fin black (Ref. 106136).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (20 of 100).
